Kconfig: Update ASan config options

Instead of enabling ASAN_IN_ROMSTAGE from Kconfig file in a
platform's dedicated directory, let's introduce a new config
option HAVE_ASAN_IN_ROMSTAGE to denote if a given platform
supports ASan in romstage.

Similary, use HAVE_ASAN_IN_RAMSTAGE to indicate
if a given platform supports ASan in ramstage. Consequently, we
no longer have to make ASan x86 specific.
